[SciPy-user] SciPy with gcc4 and gfortran on OS X

Hi folks,
I just built the latest scipy svn version on a G5 with gfortran to
see how things went.
Everything build OK, and the tests don't segfault, but all the
problems I reported on my G4 persist. Specifically, some tests fail
all the time and some fail sporadically (see below). Also, I still
get the 'WARNING: clapack module is empty' message, which Robert
informed me shouldn't be happening on OS X.
Oh well. Anything I can do to help sort out these issues?
